Gallium is a metal that has unique properties that differentiate it from other metals. One of the properties that have sparked interest among scientists is its magnetic behavior. The question of whether gallium is magnetic or not has been a topic of discussion for years.
Gallium is a soft, silvery-white metal that is liquid at room temperature. It is found in the minerals germanite and sphalerite and is often used in electronic devices and alloys. While some scientists argue that gallium is magnetic because it is a metal, others disagree. The magnetic susceptibility of gallium is a function of temperature that varies with the change in state. Moreover, gallium does not have a magnetic moment on its own, which means it cannot be magnetic.
Despite these differences in opinion, there are some facts about gallium’s magnetic properties that are widely accepted. For instance, gallium offers high magnetostriction, and it can become a permanent magnet if mixed with iron or any other permanent magnet material. The molar magnetic susceptibility of gallium is -21.6×10 -6 cm 3 /mol. This article aims to explore the topic of gallium’s magnetic properties by examining the available scientific evidence and providing a definitive answer to the question of whether gallium is magnetic or not.
What is Gallium?
Gallium is a chemical element with the symbol Ga and atomic number 31. It is a soft, silvery metal that is a liquid state at just above room temperature. Gallium is a part of the periodic table and is in group 13, which makes it similar to the other metals of the group. It was discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875.
Gallium has a metallic bond, which means that it has a high melting point and boiling point, and it is also a good conductor of electricity. It has three valence electrons and can have an oxidation state of +3. Due to its unique chemical behavior, gallium can be used in various applications.
One of the most interesting properties of gallium is its low melting point, which makes it a useful component in many alloys. Gallium is also used in the production of semiconductors, as well as in the manufacture of LEDs (light emitting diodes) due to its ability to convert electricity to light.
Gallium is a diamagnetic material, which means that it is not magnetic. However, it has a high magnetic permeability, which makes it a useful material in magnetic shielding applications. Furthermore, liquid gallium has a higher magnetic permeability than solid gallium due to its paramagnetic nature.
In conclusion, gallium is a unique chemical element with various properties that make it useful in many applications. Its low melting point, metallic bond, and chemical behavior make it a valuable component in many alloys and electronic devices. Although it is not magnetic, gallium’s high magnetic permeability makes it useful in magnetic shielding applications.

Gallium Magnetic Properties
Gallium is a chemical element with the symbol Ga and atomic number 31. It is a soft, silvery-white metal that is liquid at room temperature and is known for its unique magnetic properties.
Gallium is not magnetic in its solid state, but it does have an unpaired electron in its outer shell. This means that gallium has a magnetic moment, which is the measure of the strength and direction of its magnetic field. However, the metallic bond in gallium is overlapped, so it ultimately becomes diamagnetic.
In its liquid state, gallium can be magnetic. Scientists have discovered that gallium can become a permanent magnet if it is mixed with iron or any other permanent magnet material. The molar magnetic susceptibility of gallium is -21.6×10 -6 cm 3 /mol, which means that it is strongly diamagnetic.
Gallium offers high magnetostriction, which is the ability of a magnetic material to change its shape or dimensions when exposed to a magnetic field. This property is due to the fact that gallium has a high magnetic permeability, which is the measure of a material’s ability to conduct a magnetic field.
The magnetic susceptibility of gallium is a function of temperature, which varies with the change in the state. At low temperatures, gallium is paramagnetic, which means that it is attracted to a magnetic field. At high temperatures, gallium is diamagnetic, which means that it is repelled by a magnetic field.
In summary, gallium is not magnetic in its solid state but can be magnetic in its liquid state. Its magnetic properties are strongly temperature-dependent, and it has high magnetostriction due to its high magnetic permeability. While gallium is not a permanent magnet on its own, it can become one when mixed with other materials.
